The challengeWith segment growth and new use cases, new problems and technical concerns begin to emerge. One new key concern is security. No longer can “security through obscurity” be assumed a successful strategy. While advancements in on-orbit and launch technologies have lowered the potential for catastrophic on-orbit failure, security risks across the complete end-to-end space/ground system allow for new failure scenarios. Integrators need to look at security as it relates to the entire end-to-end system throughout the system lifecycle and not simply as a patchwork of various technologies stitched together from various suppliers evaluated at the time of launch or in a pre-launch design review. Another concern is lifetime cost. Some new-generation technologies have lower up-front costs than their predecessors, which is evident during system design and development. However, support and maintenance costs over the entire product lifecycle often become an afterthought to be solved by an undefined future operations team. At the same time, many of the traditional challenges associated with earlier space programs still hold true. Due to the costs associated with launch, satellite engineers are held to hard requirements that must be met the first time and every time.
Use of proven embedded software and simulation solutions is critical to finding issues early in the development cycle and throughout the operational life, even after supplier hardware obsolescence.

Robust connectors for harsh applications
The DTT and VSS Superseal connector series are designed as cable-to-cable connections and lock securely to the mating connector via a latch. Due to the CONEC overmould, the protection degree
IP67/IP69K is complied with for the entire connector in mated condition.
Optionally the overmoulded DT connector series comes with an LED to indicate the signal status and
protection circuit. A unique feature is the 360° visibility of the LED. The protection circuit keeps
switching and interference voltage away from the LED and connected systems.
To extend the CONEC product range in the field of connection solutions for agricultural and construction
machinery, the connectors for ISOBUS are included in the ready-made and overmoulded design.
The overmould provides a continuous IP67 protection of the housing up to the hybrid cable and is suitable
especially for harsh environments like agriculture, construction and mining industries. Connection is done
via bayonet locking.
Currently, three different cable variants are available which are specifically designed for agricultural
The cable variants differ in the cross-section of the stranded wires for ground and power with 6 mm², 10 mm² and 16 mm² ▪ ds
Seventh Axis for robots
Easy to integrate into any applicationThe Shuttle system is available in seven sizes and can be easily integrated into any application. The aluminum profiles can carry and move robots weighing up to 2,000 kg and with a payload of up to approx. 300 kg. A total of six of the seven sizes are designed for applications weighing less than 1,000 kg, making them the most slender gradation on the market. The wide range of variants enables very precise dimensioning of the axis and thus significantly reduces costs for the user.
High dynamicsThanks to the lightweight aluminum profiles, the Seventh Axis system offers very high dynamics, which is particularly advantageous for demanding handling tasks. Seventh Axis is available with a rack cover as standard, optionally with a cover for linear guide and racks or with a fully accessible cover. Individual linear axis can be designed up to twelve meters in one piece with profiles. By connecting several profiles, the reach of the robot can also be increased as required.
Significant stroke extension for KUKA‑robotsIn a current application, Rollon's Seventh Axis system has extended the maximum reach of a 245 kg KUKA welding robot of 1,636 mm by a stroke of six meters. Overall, the concept of the Seventh Axis offers greater flexibility than a robot OEM solution and is an economical alternative to steel construction for robots weighing up to 2,000 kg. ▪ ds
Miniaturised GNSS/inertial system for applications with space or weight restrictions
Flexible range of applicationADMA-Slim is typically used where space or weight is limited, but where precise motion tracking is still required – for example, for motorcycles, ATVs (All Terrain Vehicles), jet skis or snowmobiles, but also for applications in overrunnable platforms for GSTs and VRUs (such as pedestrians or cyclists).
In addition, the inertial measurement system is also suitable for vehicle dynamics testing and for ADAS evaluation in general, or specifically in accordance with Euro NCAP or NHTSA test protocols. ADAS functions include, for example, the autonomous emergency braking system (AEB) or the lane support system (LSS).
Unlimited compatibilityDue to the new and stricter Euro NCAP requirements for 2018, smaller, lighter and more compact measurement systems such as ADMA-Slim are required to be integrated directly into the remote-controlled soft targets.
These are named in the test regulations as GVT (Global Vehicle Target, Euro NCAP) or SSV (Strikeable Surrogate Vehicle, NHTSA).
Powerful technologyThe fully fledged GNSS/inertial system is based on MEMS gyroscopes and accelerometers as well as a powerful GNSS receiver. With the standard GNSS measurement method without inertial sensors, a clear view of the sky is essential for a good measurement result. In practice, however, the achievable measurement accuracy is affected by buildings, trees, fences or vehicles. The inertial measurement unit suppresses signal interference in the case of poor GNSS reception or temporary GNSS signal loss.
As a result, ADMA-Slim delivers extremely precise, smooth and continuous signals even when GNSS reception is poor.
Ease of useAs with all ADMA systems, the settings can be configured quickly in the Webinterface, as it is clearly arranged and easy to use. A further advantage: Once installed, the configuration remains stored. ADMA-Slim is compatible with all previous ADMA products and can therefore also be combined with the ADMA DELTA calculation. The GeneSys Ethernet Logger software, supplied free of charge, can be used to collect data and monitor the system status in real time.
ConclusionADMA-Slim meets the requirements of Euro NCAP and NHTSA international test standards and can therefore be used worldwide for vehicle dynamics measurements and ADAS tests, such as AEB, LSS and Car-to-Car, and particularly in situations where size and weight matter. ▪ ds
Remote maintenance ensures operational safety of large aquariums
Comparing the aquarium systems with a machine or production system in industry, a decisive difference can be seen: "If a production line fails, this is certainly annoying and associated with costs. But if the control of an aquarium fails, living organisms are immediately threatened," explains Franz-Josef Vennewald, owner and managing director of VewaTech, and continues: "We cannot risk to fail. That is why each of our systems installed throughout Europe is equipped with remote maintenance.”
VewaTech from Hamm in Westphalia/Germany offers turnkey aquarium systems since more than 25 years, from planning and production of the system components to commissioning and maintenance over the entire life cycle - including complex system technology at the highest technical level. The control technology of the aquarium technology is designed in such a way that all functions can be controlled remotely.
Data acquisition and alarmingThe aquarium systems are extensively automated. It is not intended that the personnel intervene in the control system on site. An alarm response system ensures operational safety by means of optical and acoustic signals and data transmission to the building control system. “This means that we always have all relevant data and measured values in view and can intervene long before an incident occurs,” explains Franz-Josef Vennewald. The basis for this is the remote service portal mbCONNECT24, where data, water values and operator actions are continuously logged. If a limit value is exceeded, an alarm will be immediately sent by SMS or e-mail. Thanks to data history, it is always possible to trace how a critical condition occurred. Thanks to mbCONNECT24, visitors can also access selected current data themselves via the Internet. At the Ostsee-Info-Center, for example, visitors can check the current temperature and salinity of the Baltic Sea in Eckernförde without setting foot outside their front door.

3D multi-stereo sensor with large measuring field
If a CAD data set for a component is already available, faulty deviations can be determined quickly through CAD
comparison. X-GAGE3D uses this process to examine all object features simultaneously, considerably speeding up
quality control. For object digitization, X-GAGE3D creates the CAD data itself and makes it available for
further processing in all conventional formats. X-GAGE3D is especially precise here due to its ultra-fine point
cloud technology. The minimal spacing between the data points delivers a high information density and depicts
the object surface precisely. This makes it ideally suited for both, applications in the quality lab and for
integration in an automated production line. As a flexible solution, X-GAGE3D is available in multiple formats
and therefore covers the entire spectrum of application areas and component sizes.
as quality control
Designed for easiest operation and Industrie 4.0An intuitive user interface with tile design allows for safe operation without prior experience, guaranteeing smooth operation. Equipped with Wi-Fi and the OPC/UA protocol, the sensor is also optimally primed for connected production and INDUSTRIE 4.0. X-GAGE3D furthermore complements ISRA’s range of equipment for absolute measurement. This reference system determines the absolute sensor position in the space in relation to a higher-level coordinate system, thus producing the most objective results possible. ▪ ds
Opportunity is waiting for light
The team is now assuming that the charge in Opportunity's batteries has fallen to below 24 V, causing the rover to go into the low-power default mode. In this mode, all subsystems except a mission clock are turned off.
The mission clock of the rover is programmed to wake up the computer so that it can check the power.
If the rover's computer finds that the batteries are not sufficiently charged, it goes back into standby mode. Due to the high amount of dust in Perseverance Valley, the mission engineers believe that it is unlikely for the rover to collect enough sunlight to recharge for the next few days.
maxon motors can handle this“Opportunity has braved many minor and major sand storms over the years and has always managed to recover its energy. We have no doubt that our motors will also run without trouble afterwards,” says maxon CEO Eugen Elmiger. Opportunity's six wheels are driven by maxon DC motors. The Obwalden based drive specialist supplied 35 units with diameters of 20 and 25 millimeters for the rover. The maxon motors in the wheels, for example, did more than 78 million revolutions each, under extreme environmental conditions and temperature fluctuations from -120 to +25 degrees Celsius. The experiences from this successful project are being used for the development of new motors that will soon fly to Mars on the upcoming Mars missions by NASA and ESA – to join the next scientific race. ▪ ds
